Approximated Scatter Models for Stray Light Analysis
In the absence of measured data, stray light estimates can be daunting for engineers who do not regularly make scatter calculations. Here’s how to make reasonable approximations.
Optical designers and engineers frequently need to model optical phenomena before they can accomplish component characterization. For example, for a proposal effort, they might have to estimate scatter from optical elements in order to establish a budget for stray light. Illumination engineers may do a “back-of-the-envelope” calculation to determine how energy is scattered by a diffuser plate. This article describes how to make such approximations.
